RAILROAD-SWITCH.

SPECIFICATION forming part of Letters Patent No. 278,344, dated May 29, 1883. 7 Application filed November 8, 1882. (No model.)

and to the letters and figures of referencemarked thereon. g V

Figure l of, the drawings is a top or plan view of our switch, and Fig. 2 is a cross-sectional View of the same.

.This invention has relation to railroadswitches designed to be used without frogs;

and it consists in the construction and novel arrangement of the centrally-pivoted four-rail switch-frame, having its middle rails a little longer than the outer rails, the horizontallyvibrating switch-lever, its guides and catch, and the lateral rods connecting the lower horizontal crank-arm ofthe switchlever to the ends of the switch, all as hereinafter set forth. In the accompanying drawings, the letter A designates the rails of the main track, and B those of the side track. At one end of the switch the ends of the rails A are secured to a broad bearing-plate or tie, G, and exterior to said ends are secured to said plate or tie the stops D, which are separated from the main rails by an interval. At the other end of the switch the endsof the main rails and side-track rails are secured to a bearing-plate, (3, the outer rails projecting a little farther over the plate than the inner rails to suit the circular movement of the end of the switch. This plate or tie is provided with stops D, which are located immediately outside of the ends of the outer rails and in contact therewith.-

The switch S consists of the straight rails F F and the curved rails E E, alternately arranged on a pivot-bar, a, and connectingbars b,as shown. The middle or intermediate rails, E and F, are respectively longer than the outer rails, E and F, and are arranged to describe aconvex curvature at each end of the switch when operated, the curvature centering at the pivot-bolt G, which is at the center of the switch, and connects the same to the middle plate, H. The ends of the middle switch-rails, E and F, are strongly connected by lateral bolts K at that end of the switch which is next the side track, while at the other end of the switch the outer and inner rails on each side, E and F. and E and F, are similarly connected by lateral bolts, so that, although the ends of .the switch-rails project over and rest only on the guide-plates or ties 0 and 0, their relative position is firmly secure. The middle bearing-plate or tie, H, is laterally extended to form a bearing for the lower pivot of the switch lever L, which is formed with a vertical shaft, m, a horizontal crank-arm, n, at its foot, and a horizontal operating-arm, 'P, at its upper end. The upper portion of the shaft m is journaled in a suitable frame, R, and the operating-arm P passes through between the arc-guides T, which are perforated to receive the fasteningpin a. The lever-arm a is pivoted to theinner ends of the curved horizontal rods 22, the outer ends of which are secured to the ends of the connecting-bars 1) 11 When the switchlever is moved the switch turns on its pivot G. After movement the switch is secured in position by the catch-pin a, which is passed through the perforations of the guides T.

The arrangementof switch-rails herein shown is identical with that shown in Letters Patent No. 163,198, and is therefore not broadly claimed herein, as in that patent is found two inside converging rails and two outside rails, the four being connected together.

Having described this invention, what we claim, and desire to secure by Letters Patent,

The switch described, consisting of the centrally-pivoted four-rail switch S, having its middle rails, E F, alittle longerthanits outer rails, E F, the horizontally-vibrating switchlever L, its guides T, and catch a, and the lateral rods .2, connecting its lower horizontal cranlg-arm to the ends of the switchframe, substantially as specified.

In testimonyq hat we claim the above we have hereunto subse ibed our names in the mo presence of two witness JAMES LEET. ALEXANDER (l. ISRAEL. Witnesses:
